Error when exporting: wrong-type-argument stringp nil

[tazheinrich]

I get an error, saying (wrong-type-argument stringp nil) when exporting an org-file.

Minimal example:

#+BIBLIOGRAPHY: ~/references.bib
#+PANDOC_OPTIONS: csl: ~/american-political-science-association.csl

Seeing the same thing, also with a local BIBLIOGRAPHY reference.

I've noticed parsing the org file for pandoc seems to fail here:

ox-pandoc/ox-pandoc.el

Line 1682 in aa37dc7

(org-pandoc-put-options

Particularly in (split-string val "\n") where it expects to get a string but gets a list? Might have to do with using a newer version of org? In my case it is Org mode version 9.5 (9.5-b83ae59 @ /home/uri/src/doom-emacs/.local/straight/build-28.0.50/org/)

I did though tried passing the bibliogrphy via #+PANDOC_OPTIONS: bibliography:~/.../file.bib but seeing the same error.
